UnitStash

UnitStash helps you stay in control of prepaid electricity — without sign-up, without cloud and even offline.

UnitStash works as an offline manual tracker. It is not connected to any DISCO or electricity provider. Users enter tokens/top-ups and meter readings manually.

Compatible with STS (Standard Transfer Specification) prepaid meters and 20-digit electricity tokens.

If you buy electricity tokens and keep losing them in WhatsApp, SMS or notes, UnitStash puts everything in one place and helps you plan ahead.

Key features

Token vault: save and organize your purchased tokens per meter

Readings: add your current "units" to improve accuracy

Days-left estimate: see an approximate "days left" based on your history

Low-credit alerts: get notified before you run out

Due card (PNG): generate a shareable card for roommates/family

Monthly overview: track spending and average consumption over time

Free vs Pro (one-time purchase)
Free includes 1 meter, full token storage for that meter, 3-month detailed history and basic estimates.
Pro unlocks multiple meters, full history and advanced reminders/settings.

Important notes

Estimates are approximate and based on the tokens and readings you enter.

UnitStash does not sell or generate electricity tokens. It is a personal tracker/organizer.
